To all whont 't may conccrn:

Be it known that I, JOHN KIMBLE CARLTON HOBBS, a citizen of the UnitedStates, residingin the city and county of San Francisco, State ofCalifornia, have in vented an Improvement in Butter-Boxes; and I herebydeclare the following to be a full, clear,'and exact description of thesame.

My invention relates to an improved construction of boxes which areespecially designed for the transportation of butter. It is desirable inthe Construction of such boxes to form adust-tight joint between thecover and the upper edge of the box on which it closes, to providestrong and loosely-jointed hinges about which said cover may be opened,said hinges being of such a nature that they will not be easily injuredor destroyed by the corrosive action of salt contained in the butter,and, lastly, to provide a means for fastening the cover when closed insuch a manner that it may be securely locked and at the same time easilyunlocked without danger of losing the fastening devices.

Referring to the accompanying drawings, Figure 1 is a view of the box.Fig. 2 is alateral central section through the same. Fig. 3 is a detailView of one of the hinges.

In carrying out my invention the box A, which is of sufficient depth toreceive the rolls of butter, is formed with a centrally-disposedupwardly-projecting rib, as at 2. The cover 3 has a rim around itsperiphery projecting downwardly to a suflicient depth to permit of agroove or channel4, which is made in it of such depth and slape as tofit snugly over the rib 2 of the box. This rib or bead is preferablyrounded upon the top, and the channel 4 is of similar shape, so thatwhen the cover is closed the two fit snugly together, and there is aledge exterior and interior to the rib on the upper edge of the box, asshown at 5, upon which the corresponding surfaces of the edge of thecover rest, so that the ingress of air and dust is eectually preventedwhen the cover is closed. The cover is provided with transverse cleats6-, which stifien itand prevent its warping or twisting out of shape.

In order to attach the cover to the rear edge of the box, I have shownhinges, which are formed as follows:

7 is a stout strap of metal having screwholes by which it is Securedvertically upon the rear vertical side of the box. This strap has awide-open eye 8 formed upon its npper end and projectiug just above therear edge of the box and parallel with the rib 2 of this portion.

9 is a strap adapted to be screwed upon the top 3 of the box, bent atright angles at the rear edge, extending downwardly and having thebottom bent to form a loop 10, and this is clasped around the upper barof the eye 8, which is formed upon the strap 7, fixed to the boxportion. This allows the cover to be freely turnable about the hingethus formed, and the parts of the hinge are sufliciently large and looseso that the channel 4 of the cover will easily engage with and disengagefrom the rib 2 when closing and opening the box, and no injuriousbinding or corrosion can take place which will prevent the properengaging of the parts.

-In order to secure the front part of the cover when closed, I make adeep longitudinal channel upon the front edge of the box, as shown at11. A vertical channel 12 extends upward from the center of the groove11 and serves to admit the hook-strap 13, which is fixed to the cover ofthe box, as shown, its vertical side lying fiush with the front of thebox A and the inturned lower edge 14 passing down through the slot 12and 'esting upon the bottom of the horizontal channel 11.

15 is a bolt, which may be of wood or other suitable material and isslidable horizontally within the channel ll. This channel is ofsufficient length to allow the bolt to be drawn back entirely clear ofthe inturned end 14 of thestrap, and the cover can then be raisedwithout difi'culty. When the cover is closed and the bolt is pushedforward, it engages the edge 14 of the hook-strap and prevents the coverfrom being opened.

In order to prevent the removal and loss of the bolt when the cover isopened, I have shown a plate 16 secured to the front of the box andcovering the channel 11 a sutficient distance each way from the centerto prevent the bolt from being removed. At the same time the endsof thebolt are accessible through the open ends of` the channel, so that itcan be pushed in either direction to lock or nn- IOO lock the box. Thiscombination of the tongue and groo.ve,on2,th'e:-box edges and rimiofthe; cover, the loosely-movable uniting-hinges at the rear, andsimilarly loose strap and slidable bolt-fastening at the front allowsufficient movement of the parts relatively to insure the properengage'ment of the rib and groove in closing or opening and such ameeting of the parts that the fastening can always easily be operated.

Having thus described my invention, what I claim as--new,and desire tosecure by. Letters Patent, is-'- An improved butter-receptacleconsistingof a box, a cover therefor having a rim around itsperiphery and`projectingdow'n wardly said rinandthe upper edge of thebox formed with arib andgroove joint,`hinge-plates- Secured; tothe top of the cover andbentdownwardly* over the said rim and other hinge-plates on the-boxandloosely connected with the firstnamed plates in the plane of the outersides of the box, said box having a longitudinal groove in its front anda vertical groove or slot leading therefrom, and said cover havingarstrap depending-fromits-front edgeand bent inwardly and adapted toenter said slot sothat itsbent end rests upon the bottom of thelongitudinal groove, a bolt slidable in the latter groove and adapted toengage said bent end and. lockwthe cover, ,andmeansfor retaining thebolt in its groove.

In witness whereofI have hereunto set my hand. I
